1 Introduction We are very pleased to see that you using a ELCON product and would like to express our appreciation. This documentation is valid for the product: NT1+ Multi Hardware Software version V1.364 or higher
1.1 The NT1+MULTI in use The user of the ELCON NT1+MULTI can dispose of different interface types designed for connection of a variety of terminals. These are: 1. the S/T interface 2. both a/b interfaces 3. the data interface V.24 (RS232) 4. the data interface USB (Version 1.1) The S/T interface offers connection of digital ISDN terminals via two RJ45 connectors. Apart from this, you can establish an S bus, thus linking up to eight digital ISDN terminals with the NT1+MULTI, whereby four of these terminals can be powered at the same time from the NT1+MULTI via S bus. With help of the RJ 11 plug connector, one analogue terminal can be directly connected to each of both a/b interfaces. If you have at your disposal analogue terminals, for example telephones, fax devices, modems or answering machines, you can connect them directly to the analogue interfaces at the NT1+MULTI. Your existing analogue devices are now able to provide you with a wide range of ISDN services. The data interface V.24 (RS232) or USB allows direct connection of personal computers via their COM or USB interface. The data interface V.24 and USB integrated in the device NT1+MULTI allow you problem-free connection of your PC at one data port, of which you simply have to link the network termination to a free COM interface or a free USB port. Using the delivered software you can open the door to a variety of application fields, for example internet, e-mail or computer-based fax transmission.
The Figure below shows some application fields of the NT1+MULTI.
1.2 System prerequisites for installation of the NT1+MULTI To offer usage of the whole range of services provided by the NT1+MULTI, the following conditions should be fulfilled: For local power supply, an appropriate 110 VAC or 230 VAC mains connection is required. For connection to the ISDN, you need an ISDN subscriber line (U) with line code 2B1Q and transfer protocol Euro ISDN DSS 1, which will be provided by your telecommunications network operator. Using the data interface V.24 or USB requires below given additional conditions: IBM-compatible computer running at a clock frequency of > 75 MHz Operating memory 16 Mbytes Free hard-disc memory 50 Mbytes CD-ROM disc drive Operating system Windows `95 or Windows `98 Free serial interface (COM- Port) with interface module UART 16550 (Data transfer rate > 115 kbps; better > 230 kbps) or free USB interface (USB Version 1.1) for a connection between NT1+MULTI and PC
2 Mounting 2.1 Scope of delivery NT1+MULTI – ISDN network terminating unit with two analogue interfaces, one data interface V.24 (RS232) and one data interface USB Mounting accessories (dowels, screws, drilling template) Mounting and operating instruction CD ROM with installation software Windows 95/98 and Windows 2000/NT and drivers V.24 standard modem cable SUBD 9-pole (1:1) USB standard cable
2.2 Selection of mounting site / Fastening the device NT1+MULTI The NT1+MULTI is designed for wall mounting. Select an appropriate mounting spot for the device near to the U-subscriber line from your network operator. Further, the device has to be installed near the 110/230 V mains socket, since the power plug represents the link to the supply mains. The power plug should always be easily accessible. Please make sure that there are no other concealed supply lines (e.g. power, water, gas, telecommunication supply lines) and that the device is not exposed to direct insulation. Apart from this, the device shall be protected from moisture.
2.3 Mounting the NT1+Multi The NT1+Multi is designed for use as desktop device and to be wall mounted. For mounting at wall use the attached drilling template. Place it vertical at the wall and mark the drilling holes. For a proper installation use a water level. Now drill two holes with a diameter of 6 mm. Fix the dowels (S6) in the holes. You find them together with the screw in the accessories of the NT1+Multi. Screw the the screws in the dowels. The head of the screw should have a distance to the wall of around 5 mm. Now you can hang up the NT1+Multi at these screws and continue with cabeling.
2.4 Connection facilities Below figure shows the connecting sockets of the NT1+MULTI with the corresponding designation.
A) Power supply The NT1+Multi is equipped with internal power supply. To connect the NT1+Multi to the power network, plug the Euro flat connector into the power supply socket. Thanks to the wide-range power supply, the NT1+Multi can be used either at 110V or 220V. B) U interface The ISDN line supplied from the network operator shall be connected to the clamp connectors. The wire shall remain unstripped for 5 mm and be pressed into the clamps. In order to remove the cable, press onto the orange clamps and pull out the cable. C) S interface The S/T interface is the interface for customer premises. It offers direct connection for two digital ISDN terminals via RJ45 connectors. Apart from this, you can establish an S bus, thus linking up to eight digital ISDN terminals with the NT1+MULTI, whereby four of these terminals can be powered at the same time from the NT1+MULTI via S bus. When establishing the S bus, keep in mind to terminate the bus by termination resistors (see 2.8 Configuration of DIP - switches). For establishing the S bus in Y-configuration, both ends of the bus shall be terminated by termination resistors. For more details on installation of ISDN bus and ISDN equipment, please contact your network provider or see installation instructions item 2.7. enclosed. The pin assignment of the RJ45 connectors is described in Appendix A2 D) Analogue interfaces With help of RJ 11 plug connector, one analogue terminal can be directly connected to each of both a/b interfaces. The length of such a hard-wired line shall not exceed 250 m. It allows you to use ISDN services with analogue terminal equipment without additional terminal adapters. The pin assignment of the RJ 11 connectors is described in Appendix A4.
E) Data interfaces (USB) The data interface USB (E) allows direct connection of personal computers via their USB interface. A USB cable serves for establishing a data transmission line and is linked at one side with a free USB interface at the computer, and at the other – with the NT1+MULTI. F) Data interface (V.24 / RS 232) The data interface V.24 (RS232) (F) allows direct connection of personal computers via their COM interface. A 9-pole SUB D-cable serves for establishing a data transmission line and is linked at one side with a free COM interface at the computer, and at the other – with the NT1+MULTI. A „1 to 1“ modem cable is recommended to be used as cable for data transmission. The cable shall be fixed to the devices by appropriate screws and protected from tensile loads.
2.5 Cable coupling Connect the ISDN cable of your network operator to the U interface at your NT1+MULTI. Now connect your analogue terminals. For connection you can plug-in the RJ11plugs into the determined jacks (a/b1 and a/b2). Your ISDN terminals can be connected to the corresponding jacks (S/T) by means of the RJ45-plugs. Alternatively, you can establish an S bus, to which the terminals can be linked. Now plug-in your mains plug in a 110 VAC power supply socket. Your NT1+MULTI with all terminals connected is now ready for operation, offering the manufacturer’s default settings. You can connect your PC with the NT1+MULTI as described above.
2.6 Procedure for demounting the NT1+MULTI For demounting the NT1+MULTI first disconnect all cables, beginning with the power supply cord. Now the device can be taken from the wall.
2.7 S- Bus configuration For indoor installation of ISDN S0- bus different types of bus systems can be used. For connecting one terminal equipment like PBX a point to point installation is to install. If it is necessary to connect more TE (ISDN phone, Fax, etc.) a point to multi point installation is to use. 2.7.1 Generell One feature of an installation of ISDN is the possibility to connect up to 8 different ISDN Terminals. All of theses terminals are connected parallel at a so call S0 bus. This allows you to install ISDN Fax, ISDN PC card and of course ISDN telephones
at one S0 port. All of the mentioned terminals can be used independenly of each other, depending on a free B channel. The S0 bus allows to feed power for up to 4 terminals from the NT1+Multi in normal operation mode. If you want to use more devices they need a local power supply. In case that the NT1+Multi is not powered locally one terminal can be a emergency terminal which is feed by the NT1+Multi. Prerequisite this terminal is set as emergency terminal and S0 interface is chosen for emergancy mode. Please refer therefore to the User manual of your equipment. The bus system therefore is called short passive bus. It is a point to multi point connection. It can be also installed in Y- configuration then the internal termination resistors must be switched of. In case that your bus is longer than 500 m an extended bus should be switched in the NT1+Multi. For installation of small PABX (mini switches) a point to point installation should be chosen. In the following graphics are displayed some samples of configuring a S0 bus system.

2.8 Configuration of DIP switches For a correct termination of S – bus the NT1+Multi is equipped with internal termination resistors. Depending on the installed bus system, the correct resistance can be set with DIP- switches. The switches are located in the connection area between S – interface and analogue ports.
2.9 Display elements (LED’s) The NT1+Multi is equipped with four LED’s for signalling you the state of the NT1+Multi. The LED’s have following meaning: U
ON U- interface is active Flashing Activation of U- interface OFF U- interface is not connected or U- interface is in Idle state ~ ON local power supply is connected OFF no local power supply is available The NT1+Multi operates in emergency mode B1,B2 ON B- channel is busy by a/b port or data interface Flashing The NT1+Multi performs a Reset
3 Analogue interfaces The NT1+Multi 2G supports two analogue subscriber interfaces a/b1 and a/b2. Both ports are of identical functionality and can be used independently of each other. Using an analogue telephone capable of DTMF dialling, you can modify the configuration of the relevant analogue interface as described below. Please note that the usage of some services require that your telephone is equipped with a so-called R-Flash-key. Any settings you implement at an a/b port will take effect only at that very port! Wrong settings or invalid commands are quit with a busy tone. Accepted settings are confirmed by signalling with an acknowledgement signal.
The analogue interfaces are able to offer ISDN services also to these a/b ports. That makes it possible that for instance the number of the calling party can be displayed. Prerequisite your network operator supports this service. The Supplementary Services for analogue interfaces are implemented according customer requirements. Therefore it is possible that the programming sequences in your device deviate from the one described below. Please refer to the user manual for the used DTMF sequences or contact your network operator. Also the electrical parameter for these ports are implemented according national requirements and national standards. The following services can be available with each analogue port. Many of the functions are invoked with a sequence beginning with pressing a key with flash functionality, typically the "R" key. Please change the setting of the used telephone to flash functionality; the earth key is not supported. Some of the functions will be acknowledged by tones created inside the NT1+: successful programming: a continuous tone (without time limit), not successful programming: a quickly interrupted tone (without time limit). Note: Most of the settings can also be achieved by using AT commands via the V.24 port. Please refer to chapter 6.5 for details. •
Caller ID (CLIP)
With incoming calls the calling number can be displayed if the connected analogue phone is supporting this feature, also called CLIP on analogue line. This feature has to be enabled and setup to the correct mode.
Deactivate: dial "*107*0#" Activate: dial "*107*1#" dial "*107*2#" dial "*107*3#" Setup caller id protocol: Dial "*108*0#" Dial "*108*1#" Dial "*108*2#"

(see AT commands AT**ACLIENA and AT**ACLITPYE). •
MSN (Multiple Subscriber Number)
Your ISDN connection may offer to have more than one telephone number. These numbers (MSN) can be programmed for each port. If no MSN’s are programmed, all incoming calls will be accepted. With an outgoing call the first programmed MSN (if available) will be used for displaying. 1st MSN 2nd MSN 3rd MSN Clear 1st MSN 2nd MSN 3rd MSN Set
dial: *100*# dial: *101*# dial: *102*# dial: #100# dial: #101# dial: #102#
Different ringing tones The ringing cadence can be configured depending on the called MSN. The following table describes the available ringing cadences: Dial Dial Dial

Outgoing call
The analogue device (i.e. a telephone, modem or fax machine) can use the dial method with DTMF tones or pulse dialing. The method is determined automatically by the NT1+Multi. •
Incoming call
With the default setting any incoming call causes both telephones to ring. You can program different numbers (multiple subscriber numbers = msn) for each analogue port, so only the selected (called) telephone will ring (see above and AT commands "AT**ab/1.amsn1" or "AT**ab/2.amsn1"). •
Terminal type
This terminal profile determines the service that will be used with an outgoing call and compatibility checking for incoming calls. Set:
•
*106*0# *106*1# *106*2# *106*3#
(inactive, outgoing calls only) (audio, no outgoing HLC, incoming: accept all call) (Telephony, default) (FAX).
Call waiting (CW):
While having established a voice connection an incoming call will be announced by a special tone (see note) in the telephone. This second incoming call can be accepted in two ways: 1. going on hook will disconnect the first connection; the second call will cause the telephone to ring like a normal incoming call. (The phone must be on hook for a minimum time of 1 second). or 2. "R", "2" : this will cause the first connection to go into hold, the second will automatically be accepted. or 3. "R", "1" : this will clear the first connection, the second will automatically be accepted. or 4. "R", "0" : this will clear the incoming (call waiting) call. Call waiting can be enabled by dialing *43# disabled by dialing #43# (default) (see also AT command AT**AB/1.ACW or AT**AB/2.ACW)
Note: The generated tones have the following format: call waiting with B channel: 200ms tone, 150ms pause, 200ms tone. This type of call waiting can be additionally picked up by the other telephone. call waiting without B channel: 500ms tone, 200ms pause, 500ms tone. This type of call waiting cannot be picked up by the other telephone. •
Inquiry, shuttle, transfer:
While having established a connection, you can make an inquiry to a third party. The first connection will go into hold. Establish the first connection (or accept an incoming call) Go into hold state by pressing the "R" key (Flash key) Set-up a second connection by dialing a number (external or internal connection) From this second connection you can go on in the following ways: 1. "R", "2" : Shuttle back to the first connection, the active connection will go into hold. The next pressing of "R","2" will shuttle to the second connection and so on. 2. "R", "1" : shuttle back to the first connection and clear the active connection. 2a. One internal connection: Transfer the first connected party to the second connected party by going on hook 2b. Public switch: Disconnect active connection by going on hook. The other connection will cause ringing. •
Three party conference (3PTY):
While having established a connection and having a second connection in hold state, you can invoke a three party conference. Both connections will get active at the same time. "R", "3" : activate three party conference. "R", "2" : deactivate three party conference, one connection will go into hold state, the other one stays active. Note: a three party conference cannot be used together with internal connections, so only one POTS port may be part of the conference. •
Busy on busy:
When the NT1+Multi is configured for both POTS ports with the same MSN both telephones will ring by an incoming call. If one POTS port is busy it can be selected whether the other telephone shall ring or the caller will get a busy line indication.
Activate: busy (default)
go off hook
free telephone will not ring, the caller gets
dial "*115#" go on hook Deactivate: go off hook default: free telephone will ring dial "#115#" go on hook (see also AT command AT**AB/1.AEXCL or AT**AB/2.AEXCL) •
Call Pickup:
An external incoming call for only one of the POTS ports (selected e.g. by different MSNs, while ringing or while call waiting), can be picked up by the other POTS port by entering after off hook the keys "*82#". •
Call completion to busy subscriber (CCBS):
If you get a busy line after making an outgoing call, you can activate the "call completion to busy subscriber". Your telephone will ring when the called party is no longer busy. Activate:
go off hook dial number dialled number is busy dial "R","*37#" go on hook Deactivate: go off hook dial "#37#" go on hook Interrogate: go off hook dial "*#37#" go on hook Note: The telephone switch will clear an activated „Call completion to busy subscriber“ automatically, the time for clearing is dependent of the telephone network provider. •
Malicious Call Identification (MCID):
The telephone number of a malicious caller can be registered in the public switching system. This functionality can be activated using the following scenario. Please note that the usage of malicious call identification has to be enabled by your telephone provider.
While the connection is established or was just disconnected by calling user press: "R", "*39#" the connection will be registered at your telephone provider. •
Call Bumping
This function clears a speech channel in case of data transmission using channel trunking if you wish to call to another subscriber. Call Bumping can only set with the following DTMF sequences: *301*0# *301*1# *301*2# *301*3# •
Call Bumping OFF Call Bumping for incoming calls Call Bumping for outgoing calls Call bumping for incoming and outgoing calls
Call forwarding
Three types of call forwarding are supported by the NT1+Multi: 1. Call forwarding unconditional (CFU): incoming calls will be forwarded immediately to the programmed telephone number. Activate: go off hook; dial "*21* # "; for all MSNs used on the ISDN access or dial "*21* * #"; for an MSN specified individually by the user go on hook Deactivate for all MSNs: go off hook ; dial "#21#" ; go on hook Deactivate for all individual MSN: go off hook ; dial "#21*#" ; go on hook (see also AT command AT**AB/1.AACFU or AT**AB/1.ADCFU) 2. Call forwarding busy (CFB): incoming calls will be forwarded to the programmed telephone number, if the analogue port is busy. Activate: go off hook; dial "*67* # "; for all MSNs used on the ISDN access or dial "*67* * #"; for an MSN specified individually by the user go on hook Deactivate for all MSNs: go off hook ; dial "#67#" ; go on hook Deactivate for all individual MSN: go off hook ; dial "#67*#" ; go on hook
(see also AT command AT**AB/1.AACFB or AT**AB/1.ADCFB) 3. Call forwarding no reply (CFNR): incoming calls will be forwarded to the programmed telephone number, if the device connected to the analogue port does not accept the incoming call within 30 seconds (maybe national dependent). Activate: go off hook; dial "*61* # "; for all MSNs used on the ISDN access or dial "*61* * #"; for an MSN specified individually by the user go on hook Deactivate for all MSNs: go off hook ; dial "#61#" ; go on hook Deactivate for all individual MSN: go off hook ; dial "#61*#" ; go on hook (see also AT command AT**AB/1.AACFNR or AT**AB/1.ADCFNR) If call-forwarding programming was successful, a continuous tone will be given after programming, if not successful a quickly interrupted tone will be given. Activating call forwarding can take some seconds, so the acknowledge tone may be delayed. Note: The setting of call forwarding will not be stored inside the NT1+Multi and cannot be readout. •
Call number restriction (CLIR) per call:
Before making an outgoing call you have the choice to deactivate or activate the presentation of your call number at the called side. This has to be setup up prior to the outgoing call: Deactivate: go off hook; (default) dial "*31*" dial the wished number without going on hook again. Activate: go off hook; dial "*31#" dial the wished number without going on hook again. Note: Within some ISDN networks this service has to be enabled by your telephone provider. •
Call number restriction (CLIR) permanent:
You can deactivate the presentation of your call number at the called side for all outgoing calls. This has to be setup up by:
Activate:
go off hook; dial "*31*#" go on hook Deactivate: go off hook; (default) dial "#31*#"; go on hook (see also AT command AT**AB/1.ACLIR or AT**AB/2.ACLIR) Note: Within some ISDN networks this service has to be enabled by your telephone provider. •
Hotline call
The hotline call feature allows the user to program a phone number which will be called automatically after going OFFHOOK and a programmable delay time. If the user starts normal dialing during the delay time the timer is stopped and the standard procedures for outgoing calls are performed. Program number: Activate hotline call: Deactivate hotline call: Program delay time: •
dial "*53*#" dial "*53#" dial "#53#" dial "#117*#"
delay in sec, default=5
Incoming call management
By programming this parameter the user can determine the behaviour of NT1+Multi in case of an incoming voice call which is decided to be compatible for both analogue ports. The user can decide to program the following alternatives: Broadcast dial "*300*0#" (default) Distributed dial "*300*1#" Port 1 preferred dial "*300*2#" otherwise offered to Port 2 Port 2 preferred dial "*300*3#" otherwise offered to Port 1 •

5 Using the NT1+Multi with Application Software To use the NT1+Multi with different application software and access points you have to look for the following items: Usually you need a contract with the service provider. They can help you to get an appropriate application program to run on a PC. The service provider will also supply you with the ISDN access number to call (has to be entered in the application program). The NT1+ 's parameter must fit the characteristics of the access point which be recommended in the next chapters.
5.1 Configuration for Internet To access the Internet via ISDN you have to have a contract with an Internet service provider (ISP) who runs an ISDN access. To configure the NT1+Multi you need the following information from the ISP: ISDN access number (to be entered at the PC program) Layer two protocol, usually the protocol PPP by selecting Modem NT1+Multi Internet PPP. Access protocol (to be entered at the PC system software or Internet software)
5.1.1 Internet Access There are two ways to access the Internet via ISDN: by synchronous PPP or Multilink PPP by B channel protocol X.75 It depends on the access facilities of your Internet service provider (ISP) or Point-of-presence (POP) which one you may use. For setting up internet access please follow the steps in the Dial- Up adapter of Windows operating systems. For V.24 connection use as modem type the correct modem protocol of your internet service provider. For USB connection use “ISDN line 1” as modem. For Multi Link connection set in the folder Multilink as second device “ISDN line 2”. Please get more information from your Internet provider if necessary.
5.2 Remote LAN Access To access a LAN remotely via ISDN you have to choose the appropriate protocol that is used by the ISDN router on the LAN.
6 Configuring the NT1+Multi 6.1 Introduction The ELCON NT1+Multi has been designed for the ISDN basic connection. In addition to that, the device offers two analogue interfaces for the connection of common terminating units and one V.24 interface and one USB- interface for direct computer connection. The analogue interfaces provide numerous ISDN services, thus substantially extending the service range offered by analogue phones. The settings of the NT1+Multi for the V.24 interface and the ISDN interface are called configuration. The NT1+Multi is delivered with a set of pre-set values. In the following section it will be shown how, by using the configuration commands, you can examine the configuration of the NT1+Multi and if necessary change it. The values can be stored in non volatile memory; this means they'll remain unchanged even if the power supply is disconnected. You can configure the NT1+Multi in the following ways: by using the AT command set entered by the locally connected PC. by using NT1+ Multi configuration commands entered by the locally connected PC. by using NT1Multi configurator tool by using DTMF sequences To make configuration of the NT1+Multi more comfortable, a software is enclosed to the ELCON NT1+Multi that simplifies execution of the configuration settings required. The CD-ROM supplied with each device contains: Modem driver for V.24 and USB NT1+Multi configurator 6.1.1 Hardware requirements Pentium 100 PC 8MB RAM 8MB HardDisc Space Serial Interface Windows 9x
6.2 Installation at V.24 interface The NT1+Multi is Plug-and-Play-compatible. Connect your PC via enclosed serial cable to the NT1+Multi and start the computer anew. The connected hardware will be automatically identified. Now follow the instructions displayed on your screen. Insert the disc in drive A:\ and select the desired driver.
Note: To install further drivers later on, choose from the menu »System control« the item „Modem“ and „Add driver“. After this, determine the path for your disc and select the new modem driver. To install or deinstall the driver manually, insert the disc in your drive and start »Setupta.exe«. If an installation has already been performed, you are asked whether the existing programme should be updated or the software should be deleted.
6.3 Configuration start Select from the start menu the item »NT1+Multi« and there the subitem »Configurator«. The programme is started and reads in the current settings from the NT1+Multi.
6.4 Configuration menu

6.4.3 Analogue port
Note: These settings apply to both analogue ports Entering the MSN of that port Up to three call numbers can be assigned to each analogue interface. All incoming calls on the set MSN will be accepted on that port. Selection of device type via Pull - Down menu. It is possible to determine the terminal type, e.g. facsimile or / and telephony Activation of supplementary services – Call Waiting (to signal a second incoming call during an existing call) – Calling Line Identification Restriction - Global Call Entering of the subaddress
6.4.4 Writing the data for the NT1+Multi Confirm your changes made by entering »Ok«. All changes will be sent to the device and saved there. You will be informed about the successful completion of the configuration.
6.4.5 Firmware update The configurator programme makes it possible to update the NT1+Multi firmware to a higher level. For this, start the NT1+Multi configurator. Select from the menu »General settings«, the item »Update Firmware«. The new firmware file will be chosen through a certain menu and sent to the NT+. If the update is completed successfully, a respective confirmation message will be displayed on your screen.
6.5 Configuration of USB-port Remarks: The function Call Bumping at the USB port can be set only by DTMF commands. Therefore see item 3 (Analogue interfaces). Select from the start menu the item »NT1+Multi« and there the subitem »Configurator«. The programme is started and reads in the current settings from the NT1+Multi
After reading the actual setup it will be display in the menu “VCOMM configurator”. This menu allows you to set parameters for the virtual COM port which has been installed by the driver setup. Following parameters can be set: Accept call: - reject all calls - accept all calls - accept call for the entered MSN only Settings for Bandwidth Management - Activation of Bandwidth On Demand - Time and data rate for activation of second B channel
-
Time and data rate for deactivation of second B channel Set to default parameters
After changing the parameters press “OK” button. The new configuration will be stored.
6.6 AT command set (V.24 port) Depending on firmware version of your NT1+Multi some AT- and configurator commands can not be applied.
All parameter can be changed by using an extended AT command set described in this chapter.
Please check if the factory setting will fit with your environment. The factory setting is described (highlighted) in the parameter list shown in chapter "AT command set" (see below). If you want another configuration as set in the factory default setting, please do the following steps: Connect the NT1+Multi to ISDN interface Connect the PC's com-port to the DTE interface of the NT1+Multi. Connect the power supply to the mains socket. Start a terminal emulation on your PC, please verify that the baudrate setting of the terminal emulation fits those of the NT1+Multi. Set up the parameter of the NT1Multi from the terminal emulation and save the parameter using the AT command set. Example: To change the used B channel protocol to X.75 please enter the following commands: ATB10<↵> (set protocol to X.75) AT&W<↵> (save the new configuration) Leave your terminal emulation and start your application program. With the exception of the command A/ (Repeat command) all commands begin with the prefix AT and are terminated with <↵>. Corrections in a command line are done with . A command line has a maximum of 80 characters. The command line is automatically cancelled by longer input. Blanks are ignored, capital/small letters are not significant. The parameter settings of the NT1+Multi obtained when using the AT commands can be permanently stored (AT&W) and are not lost by resetting or by leaving the AT command mode. To enter the AT command mode during an active data connection you must use the following sequence ("Escape sequence"): at least 1 sec pause <+><+><+> 1 sec pause The time gap between all three plus signs may not exceed 1 sec. The escape sequence is transmitted transparent to the remote device. Supported commands: A/
Repeat last command line
This command repeats the commands of the last entered command line. Note: No prefix AT is required. A/ A

6.6.2 AT command S register set S0 0: No automatic call acceptance, acceptance of an incoming call is controlled by the data terminal (command ATA after RING) 1: Immediate call acceptance by the terminal adapter (default)
2..n: Call acceptance through the terminal adapter after n "RING" messages. Note: The time between two ring messages can be configured using the TA+Configuration command “ringtimer“ (default = 5 sec.) S1 Ring Counter (read only) S2 Escape Character (default = 43h) S3 Carriage Return Character (default = 0Dh) S4 Line Feed Character (default = 0Ah) S5 Backspace Character (default = 1Ah) S7 Wait time for Carrier (sec) (default = 30 sec) S9 Enable PNP functionality for Windows95 (default=1, enabled) S16 Last occurred CAPI/ISDN error cause S90 Last incoming ISDN calling number (CLIP) S91 0: default 1: all unknown AT commands will be answered with OK. 2: Windows 2000 compatibility: some AT commands will be answered with OK (see list below), unknown AT commands will be answered with OK. Windows2000 AT command set change: ATBxxx All commands ATBxxx will respond OK without any functionality behind it. The B-channel protocol settings can be set with AT**PROT. AT\Nxxx All commands AT\Nxxx will respond OK without any functionality behind it. The B-channel protocol settings can be set with AT**PROT.
6.6.3 AT result codes
Result codes (numerical and verbose): Code Text Meaning 0 OK Command completed 1 CONNECT Connection established (rn = call number of remote site) 2 RING Indicates an incoming call (SETUP received) 3 NO CARRIER No synchronization (xx = ISDN error cause) 4 ERROR Illegal command or error that can not be indicated otherwise 6 NO DIALTONE No access to ISDN network (xx = ISDN error) 7 BUSY Number engaged (xx = ISDN error cause) 8 NO ANSWER No connection; called number can not be reached (xx = ISDN error cause) 9 RINGING Outgoing call is ringing at called site 19 CONNECT 64000 Connection, line speed 64 kbps Call number display: = call number of remote site
In AT command mode, call number display (does not belong to the AT command standard) can be turned on by issuing the command ATV2 or ATV3. If turned on, the call number of the caller is shown with the Connect- or Ring-message (in pointed brackets), depending on the signaling in D-channel. If the NT1+Multi is used at the public network then the call number of the remote site (including area code) is displayed. Example:
CONNECT 64000 <040890880>
Error cause display: = ISDN release (error) cause, hexadecimal Example: NO CARRIER <#34F0> In AT command mode, error cause display (does not belong to the AT command standard) can be turned on by issuing the command ATV2 or ATV3. The shown error causes use the coding defined by the CAPI definition. ISDN error causes from the ISDN network are always coded as 34xxH, where xx represents the hexadecimal version of the ISDN error cause (see page 57). All other causes are CAPI error causes (see page 59).

Stimulus codes forwarding
Setup the coding form for activation functionality inside the switch, that is done in a stimulus way. If the first key pressed after going offhook is one of the keys "*" or "#", the actual connection setup will be aborted. Further inputs will be stored locally until a pause of key inputs of 4 seconds occurs or the key "#" is entered. Hereafter all collected key entries will be sent as functional request to the public switch, as far as no locally defined programming sequence is recognized. Usually these functional codes are transmitted as “Keypad“ (KYP) elements. Some switches need these codes to be transmitted as element "Called Party Number" (CdPN), this mode has to be selected by a configuration command.
